我无法从部署的 bluemix 应用程序连接到 Compose MongoDB 服务。似乎找不到必要的证书。我原以为它会直接从环境变量 VCAP_SERVICES 中获取它。

我可以从我的本地测试环境中很好地运行它，因为我将密钥导入到 Java 中的适当密钥库中。

如果我在 bluemix 上查看他们的 node.js 示例，他们实际上是在连接期间通过了证书。但是，我在 Java API 的任何地方都找不到这个。

我相信我要么需要将此证书添加到 bluemix 上的 VM（似乎不太可能），要么我需要通过 Java 驱动程序传递它，而我不能（看不到如何）。

想法？

作为记录，这是我得到的例外：

这里记录了一些选项。例如：

将证书导入 Java 信任库文件，将文件打包到 Java 应用程序中，并通过 JAVA_OPTS 环境变量指定其路径；信任库文件可以放在资源目录下。这可用于单个应用程序：

通过使用“cf set-env”命令：

cf set-env <app> JAVA_OPTS '-Djavax.net.ssl.TrustStore=classpath:resources/config/truststore'

通过使用 manifest.yml：

---
applications:
- name: java-app
  ...
  env:
    JAVA_OPTS: '-Djavax.net.ssl.TrustStore=classpath:resources/config/truststore'
